The Formation of Human Arteriovenous Malformation Organoids and Their Characteristics.

Arteriovenous malformations (AVMs) are characterized by direct connections between arteries and veins without intervening capillaries, with the concomitant formation of abnormal vascular networks associated with angiogenesis. However, the current understanding of the diagnosis and treatment of AVMs is limited, and no in vitro disease models exist at present for studying this condition. In this study, we produced endothelial cells (ECs) in two-dimensional cultures and three-dimensional (3D) blood vessel organoids (BVOs), comparing gene expression profiles between normal and AVM organoids.

Wound healing induced by new synthetic peptide, A7-1, in C57BL/6 mouse model.

The effects of the novel synthetic peptide, A7-1, on wound healing and skin grafts were evaluated in a C57BL/6 mouse model. Two 15-mm wide circular skin excisions were made on the backs of mice and to each excision, 100 µM A7-1 or normal saline was applied daily. The treatments were applied and sutured for skin graft analysis.

MicroRNA-135b-5p Is a Pathologic Biomarker in the Endothelial Cells of Arteriovenous Malformations.

Limited studies have investigated the association between extracranial vascular malformations and cardiovascular diseases.

The discriminative role of PROX-1 immunohistochemistry between venous malformation and lymphatic malformation of the deep type with no visible diagnostic surface skin lesion.

Background: Venous malformations (VMs) are distinguished from lymphatic malformations (LMs) when specific diagnostic skin lesions are present. In the deep type, this is difficult by clinico-radiologic evaluation alone. We aimed to investigate the usefulness of lymphatic vessel endothelial cell (LEC) markers for the differential diagnosis of the deep VMs and LMs.

Indications for Furlow Double-Opposing Z-Plasty in Patients with Velopharyngeal Insufficiency following 2-Flap Palatoplasty.

Background: Various surgical methods have been developed for treating velopharyngeal insufficiency (VPI); however, the choice of surgical treatment is controversial. The pharyngeal flap, which is commonly used, has a high success rate but frequently leads to airway complications. Furlow double-opposing Z-plasty (DOZ) does not deform the velopharyngeal port; therefore, it is expected to show good speech outcomes while reducing airway complications if an appropriate indication is noted.

Boomerang latissimus dorsi flap in immediate or delayed breast reconstruction.

Background: Breast reconstruction using the latissimus dorsi (LD) flap is one of the most popular and common breast reconstruction techniques among Asian patients. There are increasing numbers of cases wherein breasts need to be reconstructed to moderate to large sizes among the Asian population. Most reconstructive surgeons use abdominal-based flaps-such as the deep inferior epigastric perforator and transverse rectus abdominis myocutaneous flap, or LD flap with an implant-to supplement the volume.

Catastrophic rhabdomyolysis following breast reconstruction operation using an abdominal flap: a case report.

Background: Rhabdomyolysis is a potentially fatal clinical syndrome resulting from the damage or breakdown of skeletal muscle, which can also lead to permanent disabilities. Based on our review of studies on rhabdomyolysis after prolonged surgeries, no other cases of rhabdomyolysis caused by muscle injury in the buttock area following breast reconstruction have been reported, making the current report the first to share information related to patient conditions and treatment progress in such cases.

Case Description: Here, we present the case of a 57-year-old Asian patient with left breast cancer.

Treatment of Sagittal Fracture of the Zygomatic Arch Root.

A sagittal fracture at the temporal root of the zygomatic arch (ZAR) often occurs as a component of zygomaticomaxillary complex (ZMC) fractures. However, this area is difficult to access, and anchorage is limited due to the unstable structure around it. Therefore, a preauricular approach using single-screw fixation is proposed, and this study reports its results and usefulness.
